No, magnets are not metal. Magnets are objects that produce a magnetic field, which can attract or repel certain types of metals, but they are typically made from materials like iron, nickel, or cobalt.
No, not all magnets have the same power. The strength of a magnet is determined by its magnetic field, which can vary depending on factors like the material it's made of and its size. Magnets can range from weak refrigerator magnets to strong neodymium magnets.
Some types of microphones, like dynamic microphones, contain magnets. The magnets are typically used in the mechanism that converts sound waves into electrical signals. Other microphones, such as condenser microphones, do not use magnets in their design.

To determine which statements about lines are true, you would typically need to provide specific statements for evaluation. Generally, some true statements about lines include that they are straight paths that extend infinitely in both directions, have no thickness, and are defined by two points. Additionally, lines can be parallel, intersecting, or perpendicular based on their orientations in a plane.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.

"In mathematics, a proof is a demonstration that if some fundamental statements (axioms) are assumed to be true, then some mathematical statement is necessarily true." (from Wikipedia)
Some of them do have magnets. Childrens alphabet magnets are an example.

Yes, it is.
Statements that always or never hold true are called "tautologies."
It is a mathematically true statement. It is grammatically incorrect.
